The Bank for International Settlements (BIS) warned of mounting risks to global financial stability in its 2026 Annual Economic Report. The report identifies massive spending on artificial intelligence infrastructure as a primary economic concern. This AI exuberance could trigger a painful investment bust with broad consequences.
The BIS cautioned that AI-related investment speed and scale currently outpace earnings. Much of this growth relies on debt, echoing the previous dot-com bubble. The five largest technology hyperscalers will likely spend over $1 trillion on AI projects through 2026.
New financial vulnerabilities include opaque circular financing where tech firms invest in AI labs that then purchase their products. If expected returns fail to materialize, a resulting pullback could sharply tighten credit conditions. This shift would pressure corporate balance sheets and create knock-on effects beyond the technology sector.
